To power the successors of Espgaluda, CAVE designed a new hardware platform based on the powerful Hitachi SH-3 processor. The graphics are handled by a dedicated FPGA and the protection resides in a CPLD. There are no more EPROM DIL sockets, instead all of the software is stored in FLASH. The PCB is equipped with an EEPROM which saves your high scores. This is a generic platform which can be reprogrammed by CAVE using JTAG technology. I.e. an Ibara may be converted to a Mushihimesama if desired

However it looks as if U23 & U24 (Sound Data) are not a part of the JTAG chain and are most likely preprogrammed before mounting.
